Brain & Other Nervous System Cancers
Brain and other nervous system cancers encompass cancerous tumors of the brain and spinal cord. Primary cancers that start in the brain are less common and are different from tumors that start in other organs and spread to the brain (metastatic or secondary brain tumors). The most common type of malignant brain tumor in Colorado, as well as the United States, is glioblastoma. In Colorado, the cumulative lifetime risk of brain and other nervous system cancer is one in 108 for males and one in 158 for females. Five-year survival with primary, malignant brain cancer was 31% for the 1990-1997 time period.
